In 2011, Adobe announced that it will stop the
development of Flash for mobile browsers. Surely, this bit of news came as a
bit of shocker to many, since a number of users had started using their mobile
devices to browse the web by this time. Luckily, the solution to this problem
was already there in the form of HTML 5.
The foundation of HTML 5 – which is the latest standard
of the HTML, was laid way back in 2004 and the very first version was launched
in 2008 in Firefox browser. Today, a number of top sites are being developed
using HTML 5.
This is mainly because of the numerous advantages
offered by HTML 5. For instance, it reduces
the need for external plug-ins, which was not the case with Flash; it provides
better error handling, it replaces scripting with more markup and makes it easy
for web developers to code web pages; it is device independent and offers
cross-platform compatibility. However, the best thing about HTML 5 is that it
is compatible with almost all the latest web browsers such as Mozilla Firefox, IE
9, Google Chrome, Safari etc, which solves the problem of discontinuity of
Flash mentioned above.
So
what exactly is HTML 5?
HTML 5 is no Rocket Science. It is basically the plain
old HTML accompanied by JavaScript and CSS. It consists of new and improved elements,
attributes, offers full CSS 3 support, audio/video tags that are easy to use,
2D/3D support, web storage, local SQL database, web app and a special type of
media element called the Canvas.
Let us look at some of the
new elements of HTML 5:
The
Doctype declaration:
The Doctype declaration in HTML 5 is a
breeze. All you need to do is define it once and then start coding. For
instance a simple layout of HTML 5 with a doctype declaration looks like this:
<!DOCTYPE html><html lang="en"><head></head><body><header></header></body></html>The Canvas element: The Canvas element is the best
thing to happen in HTML 5. It is used extensively in graphic web apps, which
needs to be dynamic in nature. It is this element, which holds immense
potential for the web pages in the years to come. <canvas id= “Canvas1” width=“100” height= “80”></canvas>
Some
new media elements:
HTML 5 also brings with itself a number of
new media elements namely, <audio>,<video>,<embed> and
<source>.
<video width=”350” height=”200” controls>
<source src=“movie1.mp4 type=”video/mp4>
</video>
Audio
<audio controls>
<source src= “abc.mp3” type=“audio/mpeg”>
</audio>
So, these were some of the highlights of HTML5. These and
numerous other features make HTML 5 the future of web technology. You can read
more about this wonderful technology on the internet, go through some of the best
sites developed using it and even use it for developing your very own web
pages. Cheers!
